[otrs] looking for help to update from OTRS 1.3.2 to 2.3.4

Hello, I am looking for someone who could help me to upgrade from my rather old OTRS 1.3.2. to the newest version (2.3.4), keeping all my customization working. Of course I will pay for this. But please, only freelancers who don't charge like a professional service, because I couldn't afford this. Please respond to info@mercator.net thanks, marc
